Answer:
45 j
Explanation:
At the top, the KE will have been converted to PE
KE = 1/2 mv^2 =PEat-top = 1/2 10 *3^9 = 45 j
The answer is <span>D- a motorcycle with a constant velocity.
Velocity is much more stable in terms of speed and distance that can be associated with the dynamics of equilibrium (balance) compared to speed alone. It brings the constant relationship between the two elements.
Speed is only focused on time of travel and not with direction. While acceleration does not show equilibrium but only a change in speed.

Answer:
the internal resistance of the battery be minimized
Explanation:
Because from
P= I²R+I²r
The amount of emf of battery delivered to the external load depends on internal resistance r such that the smaller the r the higher the emf
